A tire hanging from a tree is at rest. The force of gravity is pulling down on the tire. Another force, called tension, is pulling up on the tire. Tension is the pulling force that is transferred along the length of a string or rope. An object that is moving will stop moving when

body will stop moving if the gravity will be equal to the tension produced in the string so both the forces will cancel the influence of each other leading to the state when the body is in equilibrium  

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
